Body of Knowledge

Included in the Body of Knowledge are subtext explanations and corresponding cognitive levels for each subtopic. These details will be used by the Examination Development Committee as guidelines for writing test questions and are designed to help candidates prepare for the exam by identifying specific content within each topic that may be tested.

The subtext is not intended to limit the subject matter or be all-inclusive of what might be covered in an exam, but is intended to clarify how topics are related to the role of the certified biomedical auditor. The descriptor in parentheses at the end of each subtext entry refers to the highest cognitive level at which the topic will be tested. A more complete description of cognitive levels is provided at the end of the document.

Please Note: The Certified Biomedical Auditor (CBA) program recently underwent a Body of Knowledge refresh and starting in the November 2020 testing window, the program will be renamed to the Certified Medical Device Auditor (CMDA) and the new Body of Knowledge will be tested. Please read our Body of Knowledge Map that details the refresh process, and the differences between the 2012 CBA BoK and 2020 CMDA BoK.
